Definitions

  • the present invention relates to a seed drill with a seed storage, which is connectable via a seed distributor with a plurality of Ausbringierin, in particular coulters or seed tubes, wherein the Ausbringierin each a separating device for separating the seed grains is assigned and an image capture device with at least one camera for detecting the Seed discharge is provided.
  • the seed output should be controlled as accurately as possible, whereby not only the absolute number of grains, but also the time sequence of the discharge of the individual grains is of importance. For example, depending on the speed, the time interval between the grains discharged from a seed pipe should be as uniform as possible in order to achieve a defined distance of the deposited grains from one another.
  • the image capture device has two cameras arranged in a plane, which have mutually perpendicular viewing directions in order to be able to detect seed grains which may be hidden in one viewing direction with the other camera.
  • a similar sowing machine shows the EP 1 566 089 A1 in the riser to the distributor head of the drill having a sensor unit with a plurality of light barriers comprising each a light emitter and a light detector to visually count the seed grains.
  • the present invention is therefore an object of the invention to provide an improved seed drill of the type mentioned, which avoids the disadvantages of the prior art and the latter further develops in an advantageous manner.
  • an improved monitoring of the separation quality is to be achieved.
  • the image capturing device has a first camera, which observes the inlet of the separating device, and a second camera, which observes the outlet of the separating device.
  • the first camera the time sequence of the incoming into the separating device Seed grains and the second camera, the timing of emerging from the singulator seed grains are detected so that causal relationships between inlet and ejection clusters can be detected.
  • the two cameras of the image acquisition device can be connected to a control device for controlling at least one machine parameter as a function of the images captured by the two cameras.
  • image-dependent controllable machine parameters are fundamentally different into consideration, such as in particular a blower power, a metering, the speed of the separating device, a Verteilkopfjust réelle, a tractor speed and / or a placement depth.
  • the control device can generate corresponding actuating signals for controlling actuators, with the aid of which the said operating parameters can be changed.
  • the control device can in this case comprise an image comparison device with the aid of which the images of the first camera are compared with the images of the second camera.
  • an image evaluation device can determine causal relationships between inlet heaps and ejection heaps.
  • the image evaluation device can be designed to work statistically and determine the time course of the number of grains in the inlet of the separating device and the time course of the number of grains in the outlet of the separating device and compare with each other. It is advantageous if the image evaluation device determines, based on the images of the first camera, how and whether the grains arrive at the inlet of the separating device in succession, whereby the cause of the respective separation quality is determined. On the other hand, the image evaluation device can count the grains and / or determine their temporal sequence on the basis of the images of the second camera at the outlet of the separating device.
  • the cameras of the image capture device can be designed differently, with basically both cameras can have the same or similar training.
  • the first camera and the second camera are designed differently.
  • the first camera in the incident light method work.
  • the grains are illuminated in the inlet area, wherein the first camera detects the illuminated side of the grains.
  • the first camera can observe the grains transported on the circumference of a rotor of the separating device, which are carried along by the rotor and separated.
  • the camera can observe the circumferential section of the rotor, which, viewed in the direction of rotation of the rotor, lies downstream of a feed channel but upstream of an outlet channel.
  • the second camera can work in a further development of the invention in the transmitted light method.
  • a collimating optics with a light source irradiates the seed grains emerging at the exit of the separating device from one side, wherein the second camera observes the seed grains from the other side, so that in fact the dark side or the shadow of the individual seed grains is observed.
  • the two cameras are line scan cameras.
  • the two cameras can basically work with different exposure times.
  • the exposure times of the two cameras are in the range of 2 milliseconds to 50 milliseconds.
  • the exposure times of the cameras can be variably controlled, in particular as a function of an operating parameter of the separating device.
  • the exposure time can be changed depending on the speed of the separating device.
  • Drawn seed drill 1 is designed as an attachment and can be grown via a drawbar 2 to a tractor not shown.
  • the seed drill 1 comprises a seed storage 3 from which a desired seed quantity in the form of seeds, fertilizer granules and the like can be introduced into a delivery channel 5 through a central metering device 4, for example comprising a metering rotor.
  • a blower 6 which can be connected to the delivery channel 5, this can be done by the metering device.
  • 4 provided seed on the conveyor channel 5 and an associated riser 7 in the distribution head 8 of a seed distributor 9 are promoted.
  • the mentioned distributor head 8 distributes the incoming seed to a plurality of application elements 10, with which the distributor head 8 is connected in each case via saw lines 11.
  • the Ausbringetti comprise 10 coulters 12, see. FIG. 1 ,
  • FIG. 2 schematically shown separating device 13 is provided, which may advantageously be arranged shortly before the coulters 12 and / or the Ausbringierin 10 may be associated.
  • the separating device 13 can basically be designed differently. In the illustrated embodiment, it comprises a singulation rotor 14, on the circumference of which the seed grains run in from a feed 15 and from which they are individually pulled off via an outlet 16.
  • the separating device 13 is associated with an image capture device 17, which has a first camera 18 and a second camera 19.
  • the first camera 18 observes the inlet area of the separating device 13 FIG. 3 shows, it is directed to the peripheral portion of the dicing rotor 14 immediately behind the feeder 15.
  • a collimating optics 20 with a light emitter illuminates the said peripheral portion of the singulation rotor 14 or the seed grains coming thereon.
  • the first camera 18 detects these seed grains in the incident light method, wherein in particular the temporal entry of the grains is detected and / or detected, as and whether the grains arrive in sequence.
  • the second camera 19 observes the exit area of the separating device 18.
  • a second collimation optics 21 illuminates the seed grains ejected from the outlet 16 from one side, while the second camera 19 detects the shaded sides of the seed grains from the opposite side.
  • the second camera 19 thus operates in the transmitted light method and detects the time sequence of the emerging grains and counts them.
  • the two cameras 18 and 19 work with exposure times in the range of 50 milliseconds to 2 milliseconds, the exposure times advantageously depending on the speed of the singulation rotor 14, the seed, the illumination intensity, seed and / or illumination color and possibly alternative or further operating parameters is variably controlled.
  • the spatial resolution of the cameras 18 and 19 can also be variably selected, in particular as a function of the exposure time, the camera used, the camera lens and the geometry of the singulator, typically an object size of 8 mm to 30 mm is mapped to 128, 256 or 512 pixels ,
  • the two cameras are connected to a control device 22 which comprises an image comparison device 23 and an image evaluation device 24, by means of which causal relationships between intake and ejection clusters of seeds can be detected on the basis of the images supplied by the two cameras 18 and 19.
  • the image evaluation takes place in particular statistically with regard to the time sequence of the seed discharge times.
  • a histogram of the ejection positions can be made, advantageously about once per second.
  • control device 22 can engage in the machine control of the seed drill 1 and change various operating parameters of the drill 1, such.
  • speed of the singulation rotor 14 the speed or metering of the metering device 4
  • adjustment parameters of the distributor head 8 the filing depth of the coulters 12 and an exact longitudinal and transverse distribution and possibly other parameters.
